Reported by kevinlu0...@gmail.com, Dec 1 2016

Issue description

VULNERABILITY DETAILS
It is a out-of-bounds read vulnerability in MP4 processing. 

VERSION
Adobe Flash Player  23.0.0.207
Other versions may be affected too

REPRODUCTION CASE
put LoadMP42.swf and FG-VD-16-088_PoC.mp4 on a server and load http://127.0.0.1:8080/LoadMP42.swf?file=FG-VD-16-088_PoC.mp4
run the following command line.

Credits:
  This vulnerability was discovered by Kai Lu of Fortinet's FortiGuard Labs.

Note: I tested this case and it can be reproduced stably in standalone player(pageheap enabled)and other browsers, such as Firefox , IE on Windows 10 Pro x64 and Windows 7 x64. Repros inconsistently on Chrome ,I need more time to investigate the reason.
